Title: Displacement measuring apparatus
Inventor: KANEDA HAJIME
IPC: G01C3/06
Filed: 1986-06-09
Abstract: PURPOSE:To enhance measuring accuracy by allowing a divider to receive no effect of temp. drift and to manufacture the title apparatus inexpensively, by dividing a pulse signal as it is and cutting a DC component from division output. CONSTITUTION:A pulse generating circuit 20 generating two kinds of timing pulses not synchronous to each other, a reversal circuit 22 for reversing the signal of one timing pulse to generate an electric signal, an adder circuit 23 for also adding the output of the reversal circuit other than the output of an amplifier and a high band-pass filter 24 for removing the DC drift component of a signal after division are provided. By this constitution, even when temp. drift is generated in a divider 15, the temp. drift exerts no effect on measuring accuracy. Further, by providing a sample holding circuit 25 for sampling the output signal of the divider 15 after passing through the high band-pass filter 24 on the basis of the other timing pulse B, the output of the divider receives no effect due to the dullness of rising and the output signal sampled of the divider comes to a desired displacement output.

Title: Method for detecting drippy stain of print oil
Inventor: DAIMON YOSHIO
IPC: G01N21/89
Filed: 1985-06-19
Abstract: PURPOSE:To make the quick and exact detection of oil drippy stain possible, by receiving the fluorescence generated by irradiation with black light onto the stain of print generated by the oil dripping of the lubricant or the like in which fluorescent dye is dissolved or dispersed. CONSTITUTION:For instance, fluorescent dye is made to be of the type mixed with transparent resin ink of printing medium or the like from which drying agent is removed and mixed with lubricant at a suitable ratio.

Title: Heat exchange device and air conditioner using the device
Inventor: WATABE YOSHITO
IPC: F28F1/32
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To arrest and remove fine condensate drops in a spot situated at the upper reaches from a fan, to decrease draft resistance, and to lengthen a defrosting period by a method wherein the surface of a heat exchanger situated at the upper reaches of air is made water repellency, the surface of a downstream heat exchanger is made non-water repellency, and the fin pitches of the two heat exchangers are changed. SOLUTION: An outdoor unit 7 comprises a water repellent heat exchanger 8, a hydrophilic heat exchanger 9, and an axial flow fan 10. The two heat exchangers 8 and 9 each comprise a heat transfer pipe and a fin. In this case, the fin pitch of the hydrophilic heat exchanger 9 is increased to a value higher than that of the non- water repellent heat exchanger 8. For example, it is preferable that the fin pitch of the water repellent heat exchanger 8 is set to 1-2 mm and that of the hydrophilic heat exchanger 9 is set to 3 mm or more. Since water repellent treatment having a contact angle of 170 deg. or more is applied on the surface of the heat exchanger 8, fine condensate drops are brought into contact with the downstream heat exchanger 9 and arrested thereby.  Further, since the heat-exchange 9 has a high fin pitch, even when water drop from the heat-exchanger 8 is adhered, closure of an air flow passage due to frosting hardly occurrs.
